INKING MECHANISM FOR PRINTING-MACHINES.

To all whom it may concern:

Be it known that I, BRUCE C. WHITE, a citizen of the United States,resi'din at .New York, county of New York, and tate of New York, haveinvented certain new and useful Improvements in Inking Mechanism forPrinting-Machines, fully described and represented in the followingspecification and the accompanying drawings, forming a part of the same.

This invention relates to an improved inking mechanism for printingmachines of that type in which the ink is forced by pumps to, thedistributing cylinder or other portion of the inking apparatus so as tosupply the ink under pressure and in regulated quantity and preferablyso that the supply of ink to each column or other section of the formmay be varied as desired in accordance with the matter to be printed.

The special object of the invention isto provide a more efiicient and.satisfactory apparatus for thus supplying the ink and regulating thesupply from a convenient point and without interrupting the operation ofthe machine, and to secure greater certainty and uniformity in thesupply and distribution of the ink.

With these objects in view, the invention includes various nov,el.features, constructions and combinations of. parts in inking mechanism,and a novel pump designed especially for such use, but applicable alsoto other use and for pumping other fluids.

For a full understanding of the invention, a detailed description of aninking mechanism embodying the invention in its preferred form, and amodified form of pump, will now be given in connection with theaccompanying drawi" s forming a part of this specification, and t efeatures forming the invention then specifically pointed out in thedrawings.

Referring now to the drawings, the invention is shown in Fig. 1 asapplied in connection with a five web press having rotary printingcouples, each couple consisting 0 the form cylinder A and impressioncylinder B, the form cylinder A taking the ink from form rollers asupplied from distributing cylinder C having the usual vibrating inkdistributing rolls 0. This is a common type of such printin machines,but it will be understood that .t is is shown only for purpose ofillustration and that the invention is equally applicable to other typesofprinting machines, either reciproeating or rotary, and with anydesired type culating pipe I, through which ink is con tinuouslycirculated from tank G by any I suitable means, as, for instance, by therotary pump K, indicated in F ig. 1, so that the supply of inkinreservoirs: F is constantly .maintained under-control of a float valve,as-

hereafter described, the branch pipes H- for the separate supplyreservoirs F preferably being provided with cocks, as shown, soas to cutout of the inking system any supply reservoirs desired when theirprinting couplesv supply reservo1rs,'conduits or suppl pipes E andnozzle casings D, are shown in'Figs. 4 v

I to 3, the whole inking apparatus occupying but a small space at theside of thedistributing cylinders, so as not to substantially interferewith the desired access to the press,

v and the supply reservoirs being conveniently ing plunger 10, isprovided for each desire placed for access and adjustment of the inksupply, without interfering with the operation of the machine.

The construction and operation of the ink pumping and regulatingapparatus within the supply reservoirs F,'and of the nozzles fordelivering the ink to the distributing cylinders, are duplicates, eachof these being as follows: The interior of the supply reservoir F ispartially filled with ink, in which work the ink pumps by which the inkis forced downward through the conduits or supply pipes E, which areings formed in the bottom of the reservoir. A single acting pump, havingvertically actsection of the form, usually a column, two parallel rowsvof these pumps being shown,

the pump chambers for these pumps being formed in bars 11 extendinglengthwise of the'reservoir .F and united by cross bars 12 to form aframe open betweenthe bars 11 to receive shaft 13 carrying eccentric 14,by which the frame, With its pump cylinders and plungers, is movedsidewise and the plungers 10 reciprocated, the eccentric 14 securingthis sidewise movement of the frame" through action on yokes on crossbars 12 of the moving frame, and the vertical movement through action onvertical bars 15 mounted'to slide vertically in these yokes whileheldfrom sidewise movement therein. These bars 15 form downward extensionsof a bar 16 extendinglongitudinally of the reservoir above the pumps andwhich has arms 17 extending over the pump plungers 10 so as to engageand operate the latter on the downward movement of the plate bar 16.This bar '16 also carries arms 18 extending on opposite sides of-thebar, which arms carry pivot shaft 19 on which are loosely mounted rockarms 20, one for each plunger, having toes 21 extending inward underpacked in openflangedheads 1 of plunge rs 10, and these arms 20areformed of a sleeve'and inclosed sliding stem, so as to be extensible andspring-pressed apart by spring 22, the sleeve having a head 23 numberedto correspond with the column or section of the form supplied by itspump, and the sleeve being provided with a catch 2 adapted to engageteeth 3 for holding therock arm in adjusted position, these teeth 3being formed in the underside of arms 24 projecting in oppositedirections from central web 25 extendin upward i from bar 16, the arms24 prefera ly being made separately and secured in slots in the web 25by a coverbar 26,-as shown. The ends of the arms 24. are tied togetherby rods 27 with spacing sleeves between the arms so as to form the partscarried by bar 16 into a frame that reciprocates vertically in the frameformed by bars 11 and cross bars 12 and moves sidewise with the latterframe. I

' The shaft 13 maybe driven by any suit-' able means, but as shown isdriven by gear 28 and intermediate 29 from gear 30 on sleeve 31l'oose'ondriving shaft 32 and carrying disk '33 having handle 34 mountedtherein, thisv handle 34 having a point 35 entering a recess in disk 36keyedto shaft 3 2, so as to clutch disk 33 and sleeve 31 to the shaftfor driving the pumps when the handle 34 is thrown into the positionshown in Fig. 7, while by rocking handle 34 outward against its holdingspr ng into the position shown in Fig. 4, sleeve 31 is released fromshaft'32, .and the pumps can then be run by hand at the ,speed desiredfor testing,

runthrough the umps and pipes, if desired. The driving $113,1 0 32.maybe driven from the dcleaning or repair, or cleaning fluid may be.

press by any suitable gearing so as to'secure the proper speed, or maybe driven by separate motor, if preferred.

The ink is 'preferablymaintained at the desired level in the reservoir Fby float control, the inlet pipe H .being controlled by valve 36 underthe control of float lever 37 and float 38, which parts may-be of anysuitable construction. Circulation of ink from the side of the pumpframe at which supply pipe H enters isfprovided for by passages 39connecting side troughs 40 with a central trough 41, with which connectsa drain pipe 42, provision thus being made for draining the reservoirfrom troughs 40, 41, in which any sediment orthickened ink will collectand for washing the reservoir by running water or cleaning fluidtheredistributing cylinder or other part of the P .the outer wall of Theconduits or supply pipes E from thereservoir F have their delivery endsarranged in line along the distributing cylinder C, being grouped incasing D, as shown in; Figs. 8 and-10, this casing D being provided witha removable cover 44 for access to the pipes, and the wall '45 of thecasing adjacent to the distributing cylinder havinv openingstherethrough receiving the ends of the-pipes and through which the inkpasses to the nozzles supplying the distributing cylinder.

In the" construction shown in Figs. 8 to 10, these nozzles deliverthrough the ports in support plate 4.5 into narrow passages .46 outsideplate 45, by which the ink is distributed sidewise from the pipes tosubstantially the extent of a column or other section to be suppliedwith ink by the pipe, 20

and these passages have small dellvery orifices 4, of unobstructedcircular or other polygonal form, a sufficient number of which areformed on each passage to secure the distribution required, and the inkfrom these openings falls down the inclined face 5 of abar or nozzlepiece47mounted on: the

outer side of plate 45 and acting to form passages 46, previouslydescribed, and to divide these passages from each other. a

The inclined surface 5 extends substantially into contact withthedistributing cylinder 0, and the ink from the orifices 4 spreads inflowing down the incline so as to form a continuous thin layer or filmof ink in contact with the distributing cylinder. The small orifices orpassages 4, through which the ink is distributed from passages 46,preferably extend upward, as shown, soas to assure their beingconstantly filled with ink and prevent the entrance of air from outside,as might be the case if they were directed downward from found inpractice secures a better distnibupassages 46'. In Fig. 11 there isshown a modified construction, especially adapted for the heavy ink usedin work, in which t e ink is blown by an air onto the distributingcylinder, which it is tion of such ink. The air current or air blast, isshown as provided by an air blast pipe 48 mounted on top of the casingcover 44 and having a suitable contracting. nozzle 6 delivering acontinuous air jet, or series of jets, just behind the orifices 4. Withthis construction, also, the incline 5 is preferably used and acts, asin Figs. 8 and 9, to distribute sidewise, from orifices 4, any ink notforced by the air blasts onto the distributing cylinde r. j The casing Dis preferably adjustable towardand fromthe'distributing cylinder C, soas to secure the best positionfor theremalgazine, book and simlilar...

ceipt of the ink from the nozzles by distributing cylinder C, and forthis purpose, is shown as carried by bolts 49 securedto the press frameand having adjusting nuts 50, between which arms 51, carrying thecasing, are mounted on the bolts. Preferably, springs 52 are usedoutside the arms-51,

reservoirs F kept full to the required level by the float control ofbranch pipes H, so

that a constant suction supply to the pumps is thus maintained. The pumpchambers formed in-blocks 11 and inwhich the pump plungers 10 move arebrought by'ieccentric 14 alternately into connection with the reservoironthe upward or suction strokerof the plungers 10 and into line with theports in the reservolir bottom connecting with pipes E for the downwardor delivery stroke .of they plungers, and the vertical movement of thebar 16 and lunger operating parts carried thereby 1s secured in propertime by the eccentric 14. A measured quantity of ink is thus deliveredby each pump under fixed pressureat each stroke of the plungers 10.These valveless pumps aid materially in assuring the proper action ofthe pumps and their delivery of a fixed quantity of ink, and avoid thedifficulties incident to handling ink with valved pumps. As describedabove, the lift of each plunger 10 on the suction stroke is determlnedby the position of its rocking arm 20 which determines the time ofengagement of toe 21 with plunger head 1, and the position of the arms20 is readily adjusted by moving the numbered heads or finger pieces 23sidewise. The arrangement of the adjusting heads so that they movesidewise in adjusting the ink supply to the different through-pipe I bypump K and the supply a columns or sections, is such that the rela-,

or sections-"is readily seen, andby arranging the heads so that they arenormally in line for equal adjustment of ink for the different columnsor sections, a glance at the top of the inking mechanism on raising thecover 43 shows the relative inking of all parts of the page or pagessupplied by the reservoir. This. is clear from Fig. 4, in which thereservoir is illustrated as supplying four pages of eight columns eachwith the inking, mechanism adjusted for equal supply to all columns ontwo pages, and adjusted for varying the supply to different .modifiedconstruction of pumps and regulating means, the other parts of theapparatus being the same as above described.

In this case the plungers 10 and the blocks 11. containing the pumpchambers -of the two sets are actuated by separate eccentrics,

I the two blocks 11 being connected by cross plates 54 at opposite ends,which are vertically slotted to receive sliding blocks 55 carrying.eccentric sleeves 56 in which run eccentrics 57 on shafts .58, so thatthe rotation of-the eccentrics moves the blocks 55,

with the. frame formed by plates 54andbars 11, sidewise, and moves theblocks 55, with 'their eccentric sleeves 56, vertically. The

pump plungei's 10 carry yokes 59, the upper ends of whichare threadedonadjustlng screws 60 having finger pieces 61 extending upward intoconvenient position for access.

when the cover is lifted and preferably held in. any-adjusted positionby springs 62engaging the knurled side of the. finger pieces. Theadjustingscrews 60 carry heads 63 engaging the' eccentric rings 56 toraise the plungers 10 the'length of the suction stroke or lift'ofthe'plungers, the amount Of 'lIlk delivered thus being regulated by theposition of the screws 60, which determines'the shown as geared togetherby gears 64 op-' lift of the yok'es 59 and plungers 10 by theeccentrics. The eccentric shafts 58 may be rotated by any suitable-.means, but are .erated by gear 65 on shaft 66, which in turn is driventhrough bevel gears 67 from driving. shaft 68 outside the reservoir F,and actuated-from'the press or otherwise in any suitable manner; v Inthis construction there is shown, also, a convenient-means for cuttingout a whole page of the inkinggor such part thereof as the constructionmay be designed for,"by a single valve, which arrangement also isreadily applicable to the construction shown in Figs. 1 to 11, and abovedescribed; -For this ,purpose each row of the conduits or supply pipes Econnects with a circular valve chamber in which. is lounted arotatingvalve 69 extending over the whole row of conduits E, or such partthereof as desired, and accessible from outside the reservoir forrotation, as by the squared head 70, shown in Fig. 13. These valves 69have transverse ports7, and the bottom plate of the reservoir F isprbvided with two passages 8, 9, one connected withthe pump chamber andthe other with the reservoir,

so' that by turning ajvalve 69 into the position shown in Figs. 14 and15, the pumps in the row -corresponding'to the valve will deliver inkfrom the chamber through ports 8, 7, into the conduits or "supply pipesE, and by turning the valve into the position shown in Fig. 16, thepumps of'its row will be closed to pipes E, and the ink be circulatedthrough ports 8, 7 9, from the pump to the reservoir on the dischargestroke.

The simple rotation of a valve 69, therefore, will cut outa page, orsuch portion of the inking as the apparatus maybe designed'for, withoutinterferi g with the adjustment of the separate pu'mps. 1

- The operation of the'constructlon shown in Figs. 12 to'16 will besubstantially the same as that described in connection with Figs 1. to11, exceptas will be understood. from the drawings, so that no furtherde- I scription of operation is required.
